your vehicle is equipped with Personal Automotive Security System (PASS-Key II(R)).
This security system is designed to prevent vehicle theft by disabling fuel system
and starter unless an ignition key with a specific electrical resistance is used in the ignition key
lock cylinder. PASS-Key II(R) system operates using sensing contacts, which are located in the ignition key
lock cylinder. These contact a resistor pellet located in the ignition
key. When lock is rotated, battery voltage is applied through
appropriate fuse and resistor pellet to theft deterrent module (except
Century), or body control module (Century). Pellet resistance is then
compared with programmed value in the theft deterrent module or Body
Control Module (BCM).
System components include ignition key, ignition key lock cylinder,
theft deterrent module (except Century) or BCM (Century), theft
deterrent relay and Powertrain Control Module (PCM). The PASS-Key II(R)
system can also be supplied as a special equipment option on some
It will reset itself after about 10 minutes. You just have to wait until you hear a click and the pass key light goes off.
